T 0 all whom it may concern:

Be it known that 1, PETER S'ronzUK, citizen of the Dominion of Canada,residing at the village of Ethelbert, in the Province of Manitoba,Canada, have invented certain new and useful Improvements inThreshingand Separating Machines, of which the following is aspecification.

My invention relates to improvements in grain threshers and separators,and has for its object primarily, the improvement of the means forseparating the grain from the straw after these have passed through theusual cylinders and concave and secondly the means for operating theimproved separating decks.

With these objects in view the invention consists in the novelconstruction and combination of elements hereinafter set forth, andfully illustrated in the accompanying drawing, in which Figure 1 is aside elevation of a separating machine, a portion of the siding beingbroken away to show the separating racks or decks. Fig. 2 is a plan viewfrom above of the separating racks apart from the rest of the machine.Fig. 3 is a sectional end view of the interior of the machine taken uponthe line AB in Fig. 1. Fig. 1 is a view from below of the crank movementby which the separating racks are operated.

Referring to the drawings, in which similar'characters of referencerefer to similar parts throughout the different views, C indicates thebodyof the machine having therein suitably placed and housed thecylinder 1 and concave 2, adapted to perform their usual functions anddeliver the straw and grain in their 'threshed condition to theseparating racks-behind. The separating racks are divided into groups,each of which may consist of as many individualracks as may seemadvisable, each group being separate and distinct from the others, and.separately supported and operated. 1

In simple form as shown herein, the racks are divided into two groups Dand E the members 3 and 5 of the group D being alternately placed to themembers 4 and 6 of the group E. The members of the group D are supportedat one end by the blocks 7 and 8 carried by the cross bar 9 in turncarried by the rods 10 and 11 pivotally secured to the horizontalframepieces 12 and 13 and at the opposite end by similar blocks notshown but carried by the cross bar 14 and the pendulous rod 15 securedto the frame piece 13 and a similar rod on the opposite side of themachine notshown pivoted to the framepiece 12. Simllarly the members 1and 6 of the group E are supported at one end by the blocks 16 and 17carried by the cross bar 18, in turn carried by the rods 19 and 20pivoted to the horizontal frame pieces 12 and '13, and at the oppositeend by blocks not shown but carried by the cross bar 21 and thependulous rod 22 pivoted to the frame piece 13, and a similar rod on theopposite side of the machine pivotally connected to the frame piece 12..At this point it will be noted that still another cross bar 23 is shownin Figs. 1 and 2 crossing the machine and which bar is connected withthe members at and 6 of the group E, and supported by rods, one of which24, is shown in Fig. 1.

F indicates the grain deck or gather board, locatedbelow the separatingdecks and serving to receive the separated grain and carry it to thefanning mill shown as 25 in Fig. 1. Below the gather board F andprotected thereby from falling grain and dust is the crank mechanism G,a bottom view of which is shown in Fig. 4. This consists of a shaft 26journaledat 27 and 28 to the lower side of the sill pieces 29 and 30ofthe frame of the machine. The shaft 26 is provided in its length withthe oppositely disposedcranks 31 and 32, and 33 and 34, connectedrespectively by the rods 35, 36, 37 and 38 with the rocking arms 39, 40,11, and carried by the shafts 13 and n ournaled to thesills 29 and 30.Rods 45 and M3 connect the rockingarms 41 and 39 respectively with theends of the cross-bar18, which project as will be noted in Fig. 1,through the are shaped openings 17 in the sides of the body 6 ofthemachine. Similarly, the rocking arms 10 and 42 are connected withends of the cross bar 23 by rods, only one of'which, indicated as. 48,is shown, in Fig.

1. The rods 15 and- 16 it will be noted by reference to Fig. 3, havetheir lower ends turned at right angles to form a horizontal portiondesignatedon each respectively as 45* and 4:62 the rod 48 and itscorresponding member being provided with similarly turned portions for asimilar purpose. The ends of the turned portions of the rods are adaptedto reach and be selectively entered in the openings shown at 39 and 10*in the swinging members 39 and 40 in Fig. 1, .it

being understood that similar openings are provided in the correspondingswinging members not shown in the drawings, to receive the ends of thehorizontal portions of the rods pertaining to each. It will be notedthat there is a plurality ofthe openings 39 and 40* in the respectivemembers and that disposal of the turned portions of the rods indifferent openings will operate to diminish or increase the length ofthe movement of the straw decks as'the openings made use of are close toor removed from the pivotal points 43 and 44 of the respective members.Thus the motion of the cranks is transmitted through the rocking armsand rods to the groups D and E of separating racks, imparting to them analternately reciprocating and rising and falling motion with a tendencyto carry in a direction away from the cylinder and concaves 1- and 2toward the rear'end of the machine.

The'separating racks themselves it will be noted are of novelconstruction and clesigned to have the largest possible separatingcapacity in proportion to their size. Each of the racks consist of thelongitudinally extending spaced apart sides 49 and 50 which are of equaldimension from end to end. Along the upper edges respectively of thesides 19 and 50 are the substantially right angled triangular opensidederections II and H formed by the upwardly and rearwardly sloping pieces51 and the downwardly sloping pieces 52. The members H and H are muchlarger than the serration 'orfish back usually seen in this type of machine, and they are connected each to each bythe lateral strips 58, 5d,55 and 56 disposed in spaced relation along the faces of the upwardlysloping pieces 51 and secured thereto. It is preferable that thesestrips be quite narrow and, four in number though the number may bevaried should it appear advisable.

It will now be noted that the separating racks as'describedarepr'ac'tically of skeleton construction, and that the lateral slats58, 54:, 55' and 56, while serving to prevent the straw from droppingthrough along with the grain separated by agitatiomdo not impede-thedropping of the grain, the area of the openings between the slats,owingto their being positionedupon the up sloping pieces 51, being stillgreater than would be the open. area between the sidesI-I and H ifmeasured upon the plane of their upper edges and without the erections Hand H with their connecting lateral slats.

The open construction of the triangular members H and H in addition toits value as 'a means of increasing the separating area on the surfaceof theracks without unduly adding to their weight, also adds greatly tomeans revolves the crank shaft 26, the'crank movement being transmittedas previously mentioned through the rocking arms and rods to the groupsD and E, these are caused to reciprocate and agitate the threshed strawand grain received from the cylinder and concave, passing the materialtoward the tail end of the machine.

7 Owing to the peculiar skeleton construction of the separating racks,as described, 7 the agitation lmparted is very thorough, and

grain cannot be carried past the openings in' the racks to be blown outwith the straw on to the stack and lost, which is the mainv point soughtto be attained in the designing of the machine. a

Having thusfully described my said invention what I claim is 1. In athreshing machine,a straw deck comprising a plurality of oppositelyreciprocated sections,'each of said sections having a pair. of spacedside walls provided upon their upper edges with upwardly pro ecting opensided triangular members, and transverse slats connecting the members onone side wall with those onthe other.

2. In a threshing machine, a straw deck comprising a plurality ofsections alter nately placed and connected to form oppositelyreciprocated groups, each of sa d sections having a pair ofspaced sidewalls protransverse-slat-connected triangular ,membersghaving a rearwardinclination- .105 vided on their upper edges with open'sided i 3. In'aseparating machine, a strawdeck having longitudinally extending spacedside walls and open sided triangular mem .bers on the upper edges ofeach sidewall corresponding with those on the other, lateral slatsconnecting the points of the members on one side wall with the points ofthe corresponding members on the other side wall, slats similarlyconnecting the bases of the members and connecting slats intermediatethe slats mentioned.

In testimony whereof, I aflix my signature in the presence of twowitnesses.
